Abstract

– Prose Millet (Cheeno) and Foxtail Millet (Kaguno) which are commonly cultivated in the mid and high hill of Karnali province, Nepal, and has seen a steep decline in production and consumption in recent years. The major problem associated with production of Cheeno and kaguno is the post-harvest process of removing the protective layer (Husk) from the seed (De-husking). The traditional process of de-husking usually takes 2 hr to de-husk 1.5 per kg of said Millet grain, making them inefficient and also the commercially available millet processors are not suitable for de-husking grains to a consumable capacity. This research consists of a study to replicate and mechanize the manual process of de-husking by the use of Cam and Follower mechanism. The cam is a disc type with a conical metal chunk of a follower, maintaining momentary contact throughout the cam’s rotation to replicate the “hit” and “twist” motion of the Dhunche. The machine yielded an average overall efficiency of 61.6% for Cheeno and 44.55% for Kaguno with time reduction in processing by 69.45% and 63.88% respectively. However, some limitations in functionality followed by low efficiencies and spillage loss warranted the need for further study.
